It took until May 1, but the Hennepin County sheriff's office has finally declared the 2013 "Ice Out" for Lake Minnetonka.

The sheriff's office officially determined the Ice Out at 4 a.m. Wednesday. That's when a boat can be piloted on Lake Minnetonka through the narrows around Big Island and back to the sheriff's Water Patrol Unit in Spring Park.

The Ice Out usually takes place in mid-April. This year's Ice Out is among the latest ever recorded and is only the third time an Ice Out has taken place in May since record-keeping began in the late 1880s.

Last year, the Ice Out was on March 20 and was among the earliest dates ever for the declaration.
